This is not true. Glibc supports symbol versioning. You can use it to select old versions of used symbols. The result is a binary that can work on 20 year old distros the same as on the latest, compiled with latest compiler and Glibc.
You can also compile using old distro and old Glibc to get similar effect. Though you would miss the advances of the newer compilers.
